ChallengeAs plans were being developed for Complexe Sportif Trane,
the facility owner sought to build an arena with a mechanical
system that would provide reliable operation, be safe for
customers, simple to maintain and economically viable.
SolutionThe Complexe Sportif Trane owner contacted Trane regarding
equipment for the new facility. Trane, the only established
manufacturer offering a conventional water-cooled chiller
capable of operating at ice rink conditions, presented the
RTWD chiller as a unique solution to meet the ice rink
facility’s needs. The owner showed interest in the chiller, but
wanted to see proof of the system’s capabilities. Trane
organized a site visit to one of the many arenas that had been
operating Trane chillers in similar conditions for over fifteen
years. Gaining confidence in the approach, the sports
complex owner moved forward with the project, installing a
250-ton water-cooled RTWD Helical Rotary Chiller for the ice
rink, combined with a matching dry cooler.
Making safety a top priority
Guest and employee safety was a key consideration in the
chiller selection. When using CO2 or ammonia, if an issue
occurred, evacuation of the facility would be required and
service would need to be done by specially-trained
technicians. The Trane RTWD chiller uses 134A refrigerant,

Under planning and development for years, Complexe Sportif Trane, a 100 percent privatelyowned recreational sports facility has opened in Boischatel, Québec. The 40,000 sq ft complexincludes an ice hockey rink, as well as a gym for aerobics classes and fitness activities.
reducing safety concerns and allowing service to be
performed by any professional HVAC technician. In addition,
Trane’s typical installation uses a close circuit dry cooler that
eliminates the risk of legionella compared to other systems
using an open cooling tower for heat rejection.
Lowering first and maintenance costs
With its compact size, the Trane RTWD fit easily into the
building’s mechanical room without requiring additional floor
space or special mechanical room features necessary to meet
code when using CO2 or ammonia refrigerant, making
installation fast and less costly for the ice rink facility. The
robust design of the chiller, with two direct drive helical
rotary compressors, uses fewer moving parts, helping to
reduce annual service and maintenance costs.
The Complexe Sportif Trane owner plans to use the facility as a model to
expand the privately-owned ice hockey rink concept to other cities.
January 2015Case study
Ensuring reliability and efficiency
The direct drive helical rotary compressor design of the RTWD
chiller provides Complexe Sportif Trane with precise
temperature control and reliability. The chiller can be
configured to produce leaving-evaporator solution
temperatures as low as 10°F (-12°C), making it ideal for the
quick-freezing operation needed for the ice rink. A full
ten-year warranty is offered on the reliable RTWD chiller.
For heat recovery mode, the RTWD can be used to generate
condenser water temperatures as high as 115°F (46°C) while
producing the low solution temperatures. To maximize energy
recovery, before sending excess heat outside, the chiller’s
heat rejection is used to preheat domestic hot water, heat the
snow melt pit and the arena’s under slab, and reheat the
dehumidification unit.
Creating a comfortable indoor environment
Two Trane Precedent™ rooftop units serve the gym and
office area and a heat recovery rooftop handles the comfort
needs of the change rooms. A Trane® Performance Climate
Changer™ air handler ensures that optimal humidity levels are
maintained, while delivering dependable performance,
industry-leading efficiency, lower-cost installation and quiet
operation to meet energy, comfort and budget requirements.
Managing systems with user-friendly BAS
Complexe Sportif Trane uses a Tracer™ SC building
automation system (BAS) to monitor and control its systems.
Accessible from a PC, tablet or smartphone, the Tracer SC
allows the building owner to access systems remotely to
improve efficiency, increase comfort and reduce energy use.
The user-friendly BAS makes daily tasks such as scheduling,
making set point changes or managing alarms simple.
ResultsAfter years in planning, the 100 percent privately-owned
Complexe Sportif Trane opened in Boischatel, Québec. The
Trane RTWD chiller, Performance Climate Changer air
handler, and Tracer SC building automation system installed
in the ice arena offer reliability to help ensure the continuous
operation of the facility, a comfortable environment for
guests and efficient operation, while helping to meet project
budget parameters with lower first costs and maintenance
expenses. Using 134A refrigerant rather than CO2 or
ammonia, the RTWD chiller helps maintain a safe
environment for patrons and guests, and is competitive with
the energy savings of the alternative refrigerant chillers.
With the ice rink complex successfully opened for business,
the facility owner is looking for opportunities to expand the
concept in other cities. “The connection between Trane and
our company was very good,” said Charles Vigneault, owner,
Complexe Sportif Trane. “Trane has many service technicians,
a good reputation and outstanding sales people. We are
planning to use this as our model as we look for opportunities
to work with other cities on similar ice rink projects.”
The Trane RTWD chiller can be configured to produce low evaporator
temperatures, making it an ideal solution for quick-freezing operations,
such as the Complexe Sportif Trane ice hockey rink.
